Redland City Council will move ahead with a series of targeted investigations and drainage works aimed at reducing flood risks in parts of Redland Bay, following the release of a new report.
Redland City Mayor Jos Mitchell said the actions stemmed from a previous Council resolution seeking a clearer plan to address ongoing concerns in key waterways.
“Adopted by Council at the November meeting, a motion requested a schedule of works and timeframe for clearing flood debris from watercourses to reduce the likelihood of flooding at three locations in Redland Bay,” the Mayor said.
“At today’s General Meeting, Council resolved to note the report findings and endorse potential works in select locations as detailed in the report.”
The report examined three areas identified as potential flood risk zones:
- Weinam Creek (Cliftonville Place Park and Moores Road to creek mouth)
- Torquay Creek (62-66 Serpentine Creek Road to creek mouth)
- Pitt Street Wetlands (Salisbury Road and Hamilton Street to watercourse mouth)
Council officers assessed each site and outlined a mix of further investigations and on-ground works.
In the Weinam Creek catchment, further flood modelling has been recommended to better understand whether nearby homes are at risk and to determine what mitigation measures may be required.
At the Pitt Street Wetlands, a previous inspection in August 2025 identified dense vegetation within a bio-retention basin and water ponding issues in the channel.
Officers have recommended removing the vegetation and constructing a 30-metre concrete open drain to improve water flow.
Design work is scheduled for the 2026–27 financial year, with construction planned for 2027–28.
Meanwhile, at Torquay Creek, officers found no current flooding issues.
Given the potential environmental impacts, they recommended no additional vegetation clearing beyond standard waterway maintenance practices.
The report and Council’s endorsement of its recommendations mark the next step in addressing drainage concerns raised by residents, with further investigations and staged works expected to guide future flood mitigation efforts across the identified sites.
